Tom Lane	1afac12910	Create a new file executor/execGrouping.c to centralize utility routines ... shared by nodeGroup, nodeAgg, and soon nodeSubplan.	23 years ago
Tom Lane	5bab36e9f6	Revise executor APIs so that all per-query state structure is built in ... a per-query memory context created by CreateExecutorState --- and destroyed by FreeExecutorState. This provides a final solution to the longstanding problem of memory leaked by various ExecEndNode calls.	23 years ago
Tom Lane	1fd0c59e25	Phase 1 of read-only-plans project: cause executor state nodes to point ... to plan nodes, not vice-versa. All executor state nodes now inherit from struct PlanState. Copying of plan trees has been simplified by not storing a list of SubPlans in Plan nodes (eliminating duplicate links). The executor still needs such a list, but it can build it during ExecutorStart since it has to scan the plan tree anyway. No initdb forced since no stored-on-disk structures changed, but you will need a full recompile because of node-numbering changes.	23 years ago

Tom Lane	05e3d0ee86	Reimplementation of UNION/INTERSECT/EXCEPT. INTERSECT/EXCEPT now meet the ... SQL92 semantics, including support for ALL option. All three can be used in subqueries and views. DISTINCT and ORDER BY work now in views, too. This rewrite fixes many problems with cross-datatype UNIONs and INSERT/SELECT where the SELECT yields different datatypes than the INSERT needs. I did that by making UNION subqueries and SELECT in INSERT be treated like subselects-in-FROM, thereby allowing an extra level of targetlist where the datatype conversions can be inserted safely. INITDB NEEDED!	25 years ago
